New Plumbing Review

[ejhills]

Hello all
So the new plumbing is in place and there are no leaks.

But it seems that return water is too warm, see the openstorage. and the grunfoss pump, wood boiler, slows way down.

So this is a tarm mb55 with a grunfoss pump. 250 gallons of open storage. And 2 120 gallons of pressurised storage,. I think replumbing the exchange coil on the open storage, return side, is the solution, but I'm looking for options.

Thanks for the input

Ed

The only thing I can tell from your diagram is that you don't have boiler return temp protection on your wood boiler.

Other than that, no idea how things are circulating/controlled. No temp data either.

Pictures may or may not help.

A more detailed plumbing diagram is a must. Are the diagonal hash marks valves? Need more information in order to help.
